Title: Dropper for adhesives
IPC: B65D47/18
Filed: 1980-07-15
Abstract: A dropper (14) press fitted into the neck (16) of a cyanoacrylate adhesive dispensing container (12) includes an elongated nozzle (22) having a passageway (24) of which at least a section is of constant diameter. The inlet (44) to the nozzle (22), which is in fluid communication with an outlet (46), is defined by a sharp edged orifice. The sharp edged orifice tends to discourage depending retention of any droplets of cyanoacrylate adhesive on righting of the container (12) to maintain the inlet (44) free of residual cyanoacrylate adhesive and free of the crusting and clogging thereof which might otherwise occur. To further discourage retention of any droplets of cyanoacrylate adhesive, the inlet (44) to the passageway may be formed within a downwardly depending hollow boss (48), Fig. 4 (not shown), having a narrow annular terminal surface defined by a sharp edged perimeter and the sharp edged orifice. <IMAGE>

Title: Digital error measuring circuit for shading and registration errors in television cameras
IPC: H04N9/093
Filed: 1981-04-13
Abstract: The active video picture is divided horizontally into 13 equal blocks, and vertically into 14 bands of "checkers". During the setup mode, the signal from a selected camera 12 is fed to an A/D converter 20 in the video signal path, and to sync and pattern validation circuits 22, 24, etc., which provide control and timing signals and an electronic test pattern. Horizontal error measurement is provided via a horizontal adder/memory loop 46-49 whereby selected samples within the "blocks" of successive horizontal lines are selectively summed to provide successive pairs of summed horizontal digital data. Vertical error measurement is done simultaneously by a vertical adder/memory circuit 66-76 whereby selected adjacent samples of alternate "checkers" are selectively delayed and added, to provide successive pairs of summed vertical digital data. During a read cycle, the horizontal and vertical pairs of digital data are selectively subtracted at 56 to inherently cancel the effects of existing shading errors, blooming, crosstalk, etc., and the difference signals are D/A converted at 58. The horizontal and vertical transition and zero crossing information is established, and the transitions are compared at 60 with the electronic test pattern to derive the digital horizontal and vertical spatial error data for storage in a microprocessor memory. Shading error data are provided from the vertical adder/memory circuit and are stored in the microprocessor memory. The stored error data are subsequently retrieved and used to provide spatial and shading correction during the camera operating mode. <IMAGE>

Title: Carbon elements for bipolar trickle towers and other electrochemical cells
Inventor: HUTCHINGS IAN STANLEY
IPC: C25C7/02
Filed: 1982-10-08
Abstract: Carbon or graphite elements for use as packing material in bipolar trickle towers or as anodes in cells for recovering silver from exhausted photographic solutions are produced in the form of sheets or "waffle plates" by carbonising sheets (preferably perforated) of compacted and bonded fibrous cellulosic material (e.g. perforated hardboard, preferably laminated hardboard). Carbonisation may be affected in a single step, by heating in the absence of air, to a carbonising temperature which is high enough to impart the required electrical conductivity. Preferably, however, waffle plates or other elements of greater strength and less distortion are produced by first carbonising at a lower temperature, then impregnating with further carbonisable material (pitch, tar, resins, sugar and the like), and finally carbonising at a higher temperature.
